4,5-二氰基咪唑构筑的锌(Ⅱ)、钴(Ⅱ)配合物的合成、晶体结构及荧光性质(英文)

Syntheses, Crystal Structures and Fluorescent Properties of Two Complexes (Zn(Ⅱ) and Co(Ⅱ)) Based on 2H-Imidazole-4, 5-dicarbonitrile

以4,5-二氰基咪唑(HIMDN)配体,用常温扩散法合成了2个新颖的金属-有机配合物{[Zn2(IMDN)4(H2O)3].(H2O)3}n(1)和[Co(IMDN)2(H2O)2]n(2),并通过元素分析、红外分析、热重分析和X-射线单晶衍射对其进行了表征。结果表明配合物1中2个中心Zn(Ⅱ)离子的配位环境不同,一个是四配位,另一个是六配位。配合物2的中心钴(Ⅱ)离子为六配位。2个配合物都为一维链状结构,并且均通过氢键作用显示出三维结构。此外还研究了配合物1的荧光性质。

Two novel metal-organic complexes {[Zn2（IMDN）4（H2O）3] ·（H2O）3}, （1） and [Co（IMDN）2（H2O）2]n （2） （HIMDN =2H-imidazole-4,5-dicarbonitrile） based on HIMDN have been synthesized by the method of normal temperature diffusion, and characterized by elemental analysis, FFIR, thermal gravimetric analysis and X-ray diffraction single-crystal structural analysis. The coordination environment of two Zn （Ⅱ） ions is different in 1. One Zn （Ⅱ） ion is four-coordinated and the other is six-coordinated. The central Co （Ⅱ） ion is six-coordinated in 2. Both complexes show one dimensional （1D） chain structure and connected by hydrogen bonds to form three- dimensional structure. Moreover, the fluorescent property of complex 1 had been investigated in the solid state. CCDC： 889348, 1; 889349, 2.
